Before this, I was VERY frequently having to retry..  changing just
the gw improved things significantly, but changing it on both results
is no observable retries..  This is also the default that the example
apps in loramac uses..

eliminate the strobe code as it isn't used, this just pushes
packets back and forth..

3-4 seconds to gather all this...  need to add a blinking light to this
so it's clear that it's still starting..

This is better than using RAM, as it keeps the state between power
cycles...

all working...
